微信点餐系统中出现的小问题记录

异常一、

异常错误：Loading class com.mysql.jdbc.Driver'. This is deprecated. The new driver class iscom.mysql.cj.jdbc.Driver’. The driver is automatically registered via the SPI and manual loading of the driver class is generally unnecessary.

这个问题 是在我整合项目过程中出现的，用了最新的mysql 连接驱动 我这里用的8.0.13

			mysql
			mysql-connector-java
			8.0.13

以前版本的application.yml

spring:
  datasource:
    driver-class-name: com.mysql.jdbc.Driver
    username: root
    password: 123456
    url: jdbc:mysql://192.168.0.105/sell?characterEncoding=utf-8&useSSL=false
  jpa:
    show-sql: true
    database-platform: org.hibernate.dialect.MySQLDialect

现在按照最新官方提示支持将com.mysql.jdbc.Driver 改为 com.mysql.cj.jdbc.Driver

spring:
  datasource:
    driver-class-name: com.mysql.cj.jdbc.Driver
    username: root
    password: 123456
    url: jdbc:mysql://192.168.0.105/sell?characterEncoding=utf-8&useSSL=false
  jpa:
    show-sql: true
    database-platform: org.hibernate.dialect.MySQLDialect
